tion (literacy), of general infrastructure (telephones), of health services (hospital beds), of communication (newspapers), of mortality (expectation of life for females at birth), and the birth rate. The birth rates are official rates accepted as reasonably complete by the United Nations or as estimated by the United Nations agencies from census information for roughly the years 1960-64. These data show a high level of association between the birth rate and these selected measures of development. Collectively these variables explain some 90 percent of the variance in birth rates in Latin America. Although tills is a statistical measure of association, rather than a direct causal explanation, it confirms the view that levels of the birth rate are closely linked to development.
It will be noted that these measures relate especially to social and communication variables in which progress is being made in most countries of the less developed world. The relation of birth rates to strictly economic measures, such as per capita income and average annual growth of GNP, is morea single group. However, when the analysis is confined to each of the several major cultural regions, more consistent patterns emerge.
